In the early production of the Mars Mei VN2500 series, the controller boards lacked the ability to be upgraded to accept the newest $5 bill, hence the difference in pricing. It should be noted that both early and later productions look and perform to the same high standard. It is most important to match the 5th and 6th digits of the model # to your needs, as these as a group indicate, bezel type (affecting face and fit), and voltage type (110v or 24). There are generally 3 bill stacker sizes, designated by the 8th digit of the model #. The number 2-stacks 200 bills, #3-stacks 300 and #5-stacks 500. All stackers are easily interchanged with one another. The 9th digit designates the harness needed, letter E for a 9 pin harness and M for a mdb harness. We can help you if you’re unsure on stacker and harness choices.
